The results of unique observations of total solar eclipse
March 29, 2006 using large radio telescope RATAN-600 are
presented. The observations were made during maximal phase of the
eclipse as passage of the Sun through the multi wavelength diagram
patterns of the radio telescope. Two methods of records with different
azimuth angles were used in the range from 1cm to 50 cm. During
maximal eclipse coverage by Moon, only the fine part of the optical
disk with width about 1-3
from the North Pole was opened. The
valuable information was received due to absence of scattered solar
emission, which allowed to realize the high sensitivity at several
tens wavelengths simultaneously. It was discovered: the microwave
source which situated at the North Pole at short centimeter
wavelengths; its fine small-scale structure; the detail microwave
spectrum of northern coronal hole; the spectral-polarization features
of high-latitude prominence and the data about scattered coronal
emission in wide microwave range.
